Well...i've fixed sbrk and malloc behaves correct now, but nothing changed
in the behavior of printf. I've debugged it, and found out, that something
goes wrong, when vfprintf checks the fp. I assume that stdin/out/err is not
initialized.

After making some google-research i found out, that maybe _sinit() should be
called or the the _REENT structure should be initialized. Since i don't use
reentrancy, i'm a bit confused now...
